    WHAT CAN 30 YEARS OF DUODENAL BIOPSIES TELL US ABOUT CELIAC DISEASE?


    Jefferson Adams


    • All patients receiving elective endoscopic evaluation should be screened for celiac disease.


    Celiac.com 12/12/2016 - Studies suggest that celiac disease affects about 0.5% to 1% of the North American population. There is no good screening data based on small intestinal biopsy performed during routine endoscopic evaluation.

    Researcher Hugh James Freeman, MD CM FRCPC FACP, of the Gastroenterology unit in the Department of Medicine at the University of British Columbia in Vancouver, British Columbia, recently set out to review the detection of adult celiac disease using duodenal screening biopsies over a 30-year period.

    Dr. Freeman reviewed data from patients referred between January 1982 and December 2011 for evaluation of gastrointestinal symptoms, requiring elective investigative upper endoscopic evaluation, and who underwent duodenal biopsies to determine whether changes of adult celiac disease were present. He found a total of 9,665 patients, including 4,008 male and 5,657 female, who underwent elective endoscopy and duodenal biopsy.

    Of these, 234, about 2.5%, showed celiac-associated physical changes, including 73 males (1.8%) and 161 females (2.8%). During the first 20 years, the number of biopsy-positive patients in five-year intervals progressively decreased, while over the next 10 years, the number progressively increased.

    Dr Freeman's results indicate that celiac disease is far more common in specialist practice than has been suggested by data from healthy populations using serological screening.

    Because endoscopic duodenal biopsy is so effective in spotting celiac-related damage, Dr. Freeman suggests it be routinely considered in all patients receiving elective endoscopic evaluation.

    Celiac.com 06/08/2016 - Sometimes, certain cases can stand out and grab the attention of clinicians or researchers. Such is the case of a 62-year-old woman who was suffering from severe malabsorption, and diagnosed with celiac disease based on the findings of flat, small intestinal mucosa and HLA-DQ2 positivity, although celiac blood tests were negative.
    A team of researchers questioned the diagnosis, because the woman showed no clinical or histological improvement after a long period of strict gluten-free diet.
    The research team included U Volta, MG Mumolo, G Caio, E Boschetti, R Latorre, F Giancola, P Paterini, and R De Giorgio. They variously are affiliated with the Department of Medical and Surgical Sciences at the University of Bologna, and with the Gastroenterology Unit in the Department of Gastroenterology at the University of Pisa in Italy.
    Based on the detection of enterocyte autoantibodies, the team found that the correct diagnosis for the woman was autoimmune enteropathy. After appropriate immunosuppressive treatment, the woman experienced the disappearance of all symptoms, and a complete recovery.
    Based on this case, the team notes that doctors should consider autoimmune enteropathy in the differential diagnosis of malabsorption with severe villous atrophy, including those cases with negative celiac-related serology.

    Celiac.com 06/29/2016 - As part of a call for public comment that expired on May 30, 2016 at 8:00 PM EST, the U.S. Preventive Services Task Force issued a Draft Recommendation Statement regarding celiac disease screening.
    The draft was distributed solely for the purpose of receiving public input. It has not been disseminated otherwise by the USPSTF. The final Recommendation Statement will be developed after careful consideration of the feedback received and will include both the Research Plan and Evidence Review as a basis.
    The statement is intended for adults, adolescents, and children who do not have signs or symptoms of celiac disease. The statement is basically a call for more evidence. It expresses the USPSTF conclusion that the current evidence is insufficient to assess the balance of benefits and harms of screening for celiac disease in asymptomatic persons.
    The USPSTF website regarding this announcement includes information on the Rationale, Clinical Considerations, Other Considerations, Discussion, Recommendations of Others, and References.
    Current testing recommendations include:
    The American College of Gastroenterology recommends that asymptomatic persons with a first-degree relative who has a confirmed diagnosis of celiac disease be considered for testing. Patients with type 1 diabetes mellitus should be tested for celiac disease if there are any digestive symptoms, signs, or laboratory evidence suggestive of celiac disease.
    The U.K. National Institute for Health and Care Excellence recommends offering serologic testing for celiac disease to persons with a first-degree relative with celiac disease or persons with type 1 diabetes mellitus or autoimmune thyroid disease upon diagnosis. Serologic testing for celiac disease should be considered for persons with any of the following: metabolic bone disorder (reduced bone mineral density or osteomalacia), unexplained neurologic symptoms (particularly peripheral neuropathy or ataxia), unexplained subfertility or recurrent miscarriage, persistently elevated liver enzymes with unknown cause, dental enamel defects, Down syndrome, or Turner syndrome.
    The North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition recommends testing for celiac disease in asymptomatic children who have conditions associated with celiac disease (type 1 diabetes mellitus, autoimmune thyroiditis, Down syndrome, Turner syndrome, Williams syndrome, selective IgA deficiency, and first-degree relatives with celiac disease). It recommends testing asymptomatic children who are at risk beginning around age 3 years, provided they have had an adequate gluten-containing diet for at least 1 year before testing. It recommends that asymptomatic persons with negative serology who are at risk be considered for repeat testing.19

    Celiac.com 09/22/2016 - There really hasn't been much study done on diagnostic delays and factors associated with celiac disease, as well as on its potential impact on the course of disease.
    To get a better idea of the issue, a research team recently conducted a large systematic patient survey study among unselected celiac disease patients in Switzerland.
    The research team included SR Vavricka SR, N Vadasz, M Stotz, R Lehmann, D Studerus, T Greuter, P Frei, J Zeitz, M Scharl, B Misselwitz, D Pohl, M Fried, R Tutuian, A Fasano, AM Schoepfer, G Rogler, and L Biedermann. They are variously affiliated with the Division of Gastroenterology and Hepatology at Triemli Hospital Zurich in Zurich, Switzerland, IG Zöliakie, Basel, Switzerland, the Division of Gastroenterology and Hepatology at University Hospital Zurich, Zurich, Switzerland, the Division of Gastroenterology and Hepatology, Gastroenterology Bethanien, Zurich, Switzerland, the Division of Gastroenterology and Hepatology, Spital Tiefenau, Bern, Switzerland, the Pediatric Gastroenterology and Nutrition, MassGeneral Hospital for Children, Boston, USA,and with the Division of Gastroenterology and Hepatology, University Hospital Lausanne - CHUV, Lausanne, Switzerland.
    They broke their study down into patient-associated delays, and doctor-associated delays. They found an average total diagnostic delay of 87/24 months (IQR 5-96), with a range from 0 up to 780 months, which was fairly equally divided between doctor delay and patient delay. Both mean/median total (93.1/24 vs. 60.2/12, p<0.001) and doctors' (41.8/3 vs. 23.9/2, p<0.001) diagnostic delay were significantly higher when comparing female vs. male patients, and interestingly patients' delay was similar even after an irritable bowel syndrome diagnosis.
    Patients with a diagnostic delay shorter than 2 years showed a substantially lower dependence on steroids and/or immunosuppressants, better substitution for any nutritional deficiency, and were more likely to be symptom-free between 6 and 12 months after diagnosis.
    Regular, substantial delays in diagnosing celiac disease, are linked to worse clinical outcomes, and this data shows that such delays are significantly longer in female patients.
    This increased diagnostic delay in women is the fault of doctors, not patients, in part because the delay statistics cannot be explained by a diagnosis of IBS prior to celiac disease diagnosis.

    Celiac.com 04/24/2018 - Did you know in 2017 alone, the United States had OVER TENS OF THOUSANDS of people evacuate their homes due to natural disasters such as fires, floods, hurricanes, tornadoes and tsunamis? Most evacuation sites are not equipped to feed your family the safe gluten free foods that are required to stay healthy.  Are you prepared in case of an emergency? Do you have your Gluten Free Emergency Food Bag ready to grab and go?  
    I have already lived through two natural disasters. Neither of which I ever want to experience again, but they taught me a very valuable lesson, which is why I created a Gluten Free Emergency Food Bag (see link below). Here’s my story. If you’ve ever lived in or visited the Los Angeles area, you’re probably familiar with the Santa Ana winds and how bitter sweet they are. Sweet for cleaning the air and leaving the skies a brilliant crystal blue, and bitter for the power outages and potential brush fires that might ensue.  It was one of those bitter nights where the Santa Ana winds were howling, and we had subsequently lost our power. We had to drive over an hour just to find a restaurant so we could eat dinner. I remember vividly seeing the glow of a brush fire on the upper hillside of the San Gabriel Mountains, a good distance from our neighborhood. I really didn’t think much of it, given that it seemed so far from where we lived, and I was hungry! After we ate, we headed back home to a very dark house and called it a night. 
    That’s where the story takes a dangerous turn….about 3:15am. I awoke to the TV blaring loudly, along with the lights shining brightly. Our power was back on! I proceeded to walk throughout the house turning everything off at exactly the same time our neighbor, who was told to evacuate our street, saw me through our window, assuming I knew that our hillside was ablaze with flames. Flames that were shooting 50 feet into the air. I went back to bed and fell fast asleep. The fire department was assured we had left because our house was dark and quiet again. Two hours had passed.  I suddenly awoke to screams coming from a family member yelling, “fire, fire, fire”! Flames were shooting straight up into the sky, just blocks from our house. We lived on a private drive with only one way in and one way out.  The entrance to our street was full of smoke and the fire fighters were doing their best to save our neighbors homes. We literally had enough time to grab our dogs, pile into the car, and speed to safety. As we were coming down our street, fire trucks passed us with sirens blaring, and I wondered if I would ever see my house and our possessions ever again. Where do we go? Who do we turn to? Are shelters a safe option? 
    When our daughter was almost three years old, we left the West Coast and relocated to Northern Illinois. A place where severe weather is a common occurrence. Since the age of two, I noticed that my daughter appeared gaunt, had an incredibly distended belly, along with gas, stomach pain, low weight, slow growth, unusual looking stool, and a dislike for pizza, hotdog buns, crackers, Toast, etc. The phone call from our doctor overwhelmed me.  She was diagnosed with Celiac Disease. I broke down into tears sobbing. What am I going to feed my child? Gluten is everywhere.
    After being scoped at Children's Hospital of Chicago, and my daughters Celiac Disease officially confirmed, I worried about her getting all the nutrients her under nourished body so desperately needed. I already knew she had a peanut allergy from blood tests, but just assumed she would be safe with other nuts. I was so horribly wrong. After feeding her a small bite of a pistachio, which she immediately spit out, nuts would become her enemy. Her anaphylactic reaction came within minutes of taking a bite of that pistachio. She was complaining of horrible stomach cramps when the vomiting set in. She then went limp and starting welting. We called 911.
    Now we never leave home without our Epipens and our gluten free food supplies. We analyze every food label. We are hyper vigilant about cross contamination. We are constantly looking for welts and praying for no stomach pain. We are always prepared and on guard. It's just what we do now. Anything to protect our child, our love...like so many other parents out there have to do every moment of ever day!  
    Then, my second brush with a natural disaster happened, without any notice, leaving us once again scrambling to find a safe place to shelter. It was a warm and muggy summer morning, and my husband was away on a business trip leaving my young daughter and me to enjoy our summer day. Our Severe Weather Alert Radio was going off, again, as I continued getting our daughter ready for gymnastics.  Having gotten used to the (what seemed to be daily) “Severe Thunderstorm warning,” I didn’t pay much attention to it. I continued downstairs with my daughter and our dog, when I caught a glimpse out the window of an incredibly black looking cloud. By the time I got downstairs, I saw the cover to our grill literally shoot straight up into the air. Because we didn’t have a fenced in yard, I quickly ran outside and chased the cover, when subsequently, I saw my neighbor’s lawn furniture blow pass me. I quickly realized I made a big mistake going outside. As I ran back inside, I heard debris hitting the front of our home.  Our dog was the first one to the basement door! As we sat huddled in the dark corner of our basement, I was once again thinking where are we going to go if our house is destroyed. I was not prepared, and I should have been. I should have learned my lesson the first time. Once the storm passed, we quickly realized we were without power and most of our trees were destroyed. We were lucky that our house had minimal damage, but that wasn’t true for most of the area surrounding us.  We were without power for five days. We lost most of our food - our gluten free food.
    That is when I knew we had to be prepared. No more winging it. We couldn’t take a chance like that ever again. We were “lucky” one too many times. We were very fortunate that we did not lose our home to the Los Angeles wildfire, and only had minimal damage from the severe storm which hit our home in Illinois.
      
    In 2017 alone, FEMA (Federal Emergency Management Agency) had 137 natural disasters declared within the United States. According to FEMA, around 50% of the United States population isn’t prepared for a natural disaster. These disasters can happen anywhere, anytime and some without notice. It’s hard enough being a parent, let alone being a parent of a gluten free family member. Now, add a natural disaster on top of that. Are you prepared?

    Celiac.com 04/23/2018 - A team of researchers recently set out to learn whether celiac disease patients commonly suffer cognitive impairment at the time they are diagnosed, and to compare their cognitive performance with non-celiac subjects with similar chronic symptoms and to a group of healthy control subjects.
    The research team included G Longarini, P Richly, MP Temprano, AF Costa, H Vázquez, ML Moreno, S Niveloni, P López, E Smecuol, R Mazure, A González, E Mauriño, and JC Bai. They are variously associated with the Small Bowel Section, Department of Medicine, Dr. C. Bonorino Udaondo Gastroenterology Hospital; Neurocience Cognitive and Traslational Institute (INECO), Favaloro Fundation, CONICET, Buenos Aires; the Brain Health Center (CESAL), Quilmes, Argentina; the Research Council, MSAL, CABA; and with the Research Institute, School of Medicine, Universidad del Salvador.
    The team enrolled fifty adults with symptoms and indications of celiac disease in a prospective cohort without regard to the final diagnosis.  At baseline, all individuals underwent cognitive functional and psychological evaluation. The team then compared celiac disease patients with subjects without celiac disease, and with healthy controls matched by sex, age, and education.
    Celiac disease patients had similar cognitive performance and anxiety, but no significant differences in depression scores compared with disease controls.
    A total of thirty-three subjects were diagnosed with celiac disease. Compared with the 26 healthy control subjects, the 17 celiac disease subjects, and the 17 disease control subjects, who mostly had irritable bowel syndrome, showed impaired cognitive performance (P=0.02 and P=0.04, respectively), functional impairment (P<0.01), and higher depression (P<0.01). 
    From their data, the team noted that any abnormal cognitive functions they saw in adults with newly diagnosed celiac disease did not seem not to be a result of the disease itself. 
    Their results indicate that cognitive dysfunction in celiac patients could be related to long-term symptoms from chronic disease, in general.

    Celiac.com 04/21/2018 - Dear Friends and Readers,
    I have been writing articles for Scott Adams since the 2002 Summer Issue of the Scott-Free Press. The Scott-Free Press evolved into the Journal of Gluten Sensitivity. I felt honored when Scott asked me ten years ago to contribute to his quarterly journal and it's been a privilege to write articles for his publication ever since.
    Due to personal health reasons and restrictions, I find that I need to retire. My husband and I can no longer travel the country speaking at conferences and to support groups (which we dearly loved to do) nor can I commit to writing more books, articles, or menus. Consequently, I will no longer be contributing articles to the Journal of Gluten Sensitivity. 
    My following books will still be available at Amazon.com:
    Gluten-free Cooking for Dummies Student's Vegetarian Cookbook for Dummies Wheat-free Gluten-free Dessert Cookbook Wheat-free Gluten-free Reduced Calorie Cookbook Wheat-free Gluten-free Cookbook for Kids and Busy Adults (revised version) My first book was published in 1996. My journey since then has been incredible. I have met so many in the celiac community and I feel blessed to be able to call you friends. Many of you have told me that I helped to change your life – let me assure you that your kind words, your phone calls, your thoughtful notes, and your feedback throughout the years have had a vital impact on my life, too. Thank you for all of your support through these years.

    Celiac.com 04/20/2018 - A digital media company and a label data company are teaming up to help major manufacturers target, reach and convert their desired shoppers based on dietary needs, such as gluten-free diet. The deal could bring synergy in emerging markets such as the gluten-free and allergen-free markets, which represent major growth sectors in the global food industry. 
    Under the deal, personalized digital media company Catalina will be joining forces with Label Insight. Catalina uses consumer purchases data to target shoppers on a personal base, while Label Insight works with major companies like Kellogg, Betty Crocker, and Pepsi to provide insight on food label data to government, retailers, manufacturers and app developers.
    "Brands with very specific product benefits, gluten-free for example, require precise targeting to efficiently reach and convert their desired shoppers,” says Todd Morris, President of Catalina's Go-to-Market organization, adding that “Catalina offers the only purchase-based targeting solution with this capability.” 
    Label Insight’s clients include food and beverage giants such as Unilever, Ben & Jerry's, Lipton and Hellman’s. Label Insight technology has helped the Food and Drug Administration (FDA) build the sector’s very first scientifically accurate database of food ingredients, health attributes and claims.
    Morris says the joint partnership will allow Catalina to “enhance our dataset and further increase our ability to target shoppers who are currently buying - or have shown intent to buy - in these emerging categories,” including gluten-free, allergen-free, and other free-from foods.
    The deal will likely make for easier, more precise targeting of goods to consumers, and thus provide benefits for manufacturers and retailers looking to better serve their retail food customers, especially in specialty areas like gluten-free and allergen-free foods.

    Celiac.com 04/19/2018 - Previous genome and linkage studies indicate the existence of a new disease triggering mechanism that involves amino acid metabolism and nutrient sensing signaling pathways. In an effort to determine if amino acids might play a role in the development of celiac disease, a team of researchers recently set out to investigate if plasma amino acid levels differed among children with celiac disease compared with a control group.
     
    The research team included Åsa Torinsson Naluai, Ladan Saadat Vafa, Audur H. Gudjonsdottir, Henrik Arnell, Lars Browaldh, and Daniel Agardh. They are variously affiliated with the Institute of Biomedicine, Department of Microbiology & Immunology, Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden; the Institute of Clinical Sciences, Sahlgrenska Academy at the University of Gothenburg, Gothenburg, Sweden; the Department of Pediatric Gastroenterology, Hepatology and Nutrition, Karolinska University Hospital and Division of Pediatrics, CLINTEC, Karolinska Institute, Stockholm, Sweden; the Department of Clinical Science and Education, Karolinska Institute, Sodersjukhuset, Stockholm, Sweden; the Department of Mathematical Sciences, Chalmers University of Technology, Gothenburg, Sweden; the Diabetes & Celiac Disease Unit, Department of Clinical Sciences, Lund University, Malmö, Sweden; and with the Nathan S Kline Institute in the U.S.A.
    First, the team used liquid chromatography-tandem mass spectrometry (LC/MS) to analyze amino acid levels in fasting plasma samples from 141 children with celiac disease and 129 non-celiac disease controls. They then crafted a general linear model using age and experimental effects as covariates to compare amino acid levels between children with celiac disease and non-celiac control subjects.
    Compared with the control group, seven out of twenty-three children with celiac disease showed elevated levels of the the following amino acids: tryptophan; taurine; glutamic acid; proline; ornithine; alanine; and methionine.
    The significance of the individual amino acids do not survive multiple correction, however, multivariate analyses of the amino acid profile showed significantly altered amino acid levels in children with celiac disease overall and after correction for age, sex and experimental effects.
    This study shows that amino acids can influence inflammation and may play a role in the development of celiac disease.
